Topic: Life span of typical roof air unit

Posted By: TominTampa on 06/10/17 09:11pm

Hello All,
Can anyone pipe in with an average lifespan of a ducted roof air unit? I can't really find anything on the internet that gives any idea. - Tom

I doubt that anyone here can authoritatively answer that. I can tell you that the 22 year old A/C's on a previous RV we owned are still working fine. As are the 16 year old A/C's on our current coach.

Ours is 13 years old and we're fulltime the last 7 years and it gets used for both hot and cold it's a heat pump.

Our heat pumps are now 13 years old. They are kept clean and still working.
Thought I had a bad capicator a few days ago. It was jut one unit set lower on the thermostat.
We did replace a capictator two years ago.

It really depends on where you are.
Here in Western Washington they will probably out last the RV 6~10 times but in Florida, who knows!

Covered storage, open air storage, humid climate, dry climate?? Lots of things likely effect the lifespan. My RV is 13 years old and both still work fine. I did replace the covers a couple of years ago as they were brittle and falling apart.

We have the Dometic Brisk Air units on our 17 year coach and just this year had to replace the control modules in both and a blown start capacitor in one.

My old coach a/c units are 23 years old and my present coach ones are 15 years old. That's in Texas heat.

We fulltime. We bought our Phaeton new in 2005. Our rear Coleman heatpump is 12 years old, only repairs have been the addition of a hard start capacitor and a new thermostat. We are on our 4th Coleman in the front of the RV, plus a thermostat at 6 months and a control board on one of the units. When they failed fatally, it was always the compressor that locked up. Both ducted heatpump units are the same size, 15,000 Btus

On our current MH the first one was replaced under warranty within the first year, the second one now needs replacing.

Prior to that every MH we ever owned still had the original AC on it, with the oldest being 20 years old.

I'll say it...they just don't make them like they used to.

Depends on what you call it's life, as anything can be repaired.
If anything that might go wrong, sends it to the dump, then not long in many cases.
I give up, when the refrigerant leaks out and whereas it becomes cost ineffective, unless you're an a/c guy and already have everything you need.
We sold our last coach at 18yrs old, with some repairs to the front unit, but nothing to the rear. They were Dometic. We now have Coleman heat pumps and within our year of ownership, I replaced the start capacitor. Having said that, I have no way of knowing their history or with the other rig, that we owned for 9yrs.

OK, thanks for all the inputs everyone. It sounds to me like it's probably more longer than shorter. Thanks again. - Tom

Mine original A/C units were 13500 but would not cool the MH very well in 100 plus degree climate. Now I have 2-15000 btu units and they work much better in 100 plus climate.

Yeah and must say, they are pretty good for the most part and some brands seem to last for a very long time. I was partial to Dometic, so hope these Coleman's will treat me, just as well or better.
